| Abstract: |
| The mechanical performance of some complex structures in various application fields is analyzed with the employment of MSC/NASTRAN software system,such as the vibration and stability analyses of fore instrument-cabin of certain missile,the dynamic response of a kind of launch vehicle,the analysis of structure integrity of solid rocket motor and impact response of mountain rock,etc. Meanwhile some experiences are gathered in building finite element models for static,dynamic,free vibration and transient response of complex structures in the application of MSC/NASTRAN software system. |
